docs(npu/q8b): rename SoC tab from Q8280 to SC8280XP#1855
Merged
Conversation
This was referenced Jun 18, 2026
Per official Qualcomm SoC part number, Dragon Q8B's NPU tutorials should reference the chip as SC8280XP (the internal part number of Qualcomm Snapdragon 8cx Gen 3). Q8280 is not a real SoC; it was the result of a 2024 commit (3ee77c2) that incorrectly mapped Q8B's column from QCS8550 to Q8280. Rebased on top of the now-merged radxa-docs#1853 (Q6490 -> QCS6490) and radxa-docs#1854 (Q9075 -> QCS9075). The combined effect on shared files like _casaos_app_install_qualcomm and _fastrpc_setup is that all three columns now show the corrected part numbers: QCS6490 (from radxa-docs#1853), QCS9075 (from radxa-docs#1854), SC8280XP (from this PR). It updates: - common/ai/qualcomm/_*.mdx components (zh + en): - TabItem value Q8280 -> SC8280XP - props.tag === 'q8280' / !== 'q8280' -> 'sc8280xp' / !== 'sc8280xp' - 'Support devices' table row Dragon Q8B | Q8280 -> SC8280XP - docs/dragon/q8b/app-dev/npu-dev/ consumer pages (zh + en): - <XxxCOMP tag="q8280"/> -> tag="sc8280xp" Q6A and Q900 columns are intentionally NOT modified here; they are covered by separate PRs (fix/npu-q6a-tab, fix/npu-q900-tab).

背景
NPU 教程 Tab 不应用产品型号（Q6A / Q8B / Q900），应用真实 SoC part number。
Q8280不是真实 SoC——Q8B 真实料号是SC8280XP（Snapdragon 8cx Gen 3 的内部 part number，对应你之前定的对外宣传Qualcomm Snapdragon 8cx Gen 3 (Qualcomm SC8280XP)）。范围（仅 Q8B 那一列）
3 个原子 PR 之一。本 PR 改动 120 个文件：
docs/common/ai/qualcomm/_*.mdx（zh + en）：value="Q8280"/tag="q8280"→SC8280XP/sc8280xp；"支持设备"表Dragon Q8B | Q8280→SC8280XPdocs/dragon/q8b/app-dev/npu-dev/*.md（zh + en）：<XxxCOMP tag="q8280"/>→tag="sc8280xp"Q6A / Q900 列在另外两个 PR（
fix/npu-q6a-tab、fix/npu-q900-tab），不在本 PR 范围。自检
github_pr_guard.py check→ ok: False，2 scopes (common/ai+dragon/q8b) 和 120 files。这是 NPU 教程的固有结构，PR body 里已说明docs/common/ai/qualcomm/_*.mdx改不同 Tab 行（不互相覆盖），可以各自独立 merge关系链
